Solving systems by substitution
y=x+2 y=2x-5

Answers

Answer 1

Answer: So first I recommend you line it up like this:
y=x+2
y=2x-5
So, you can plug in y (probably the one that equals x+2) and the equation turns into:
x+2=2x-5
You subtract x from both sides and get:
2=x-5
then, you add 5 to both sides:
x=7
And that is what x equals.

A chorus is a group of twelve or more members who sang and danced as a part of their commentary about a play

Answers

Answer: The correct answer is : True

Explanation: At the beginning the choirs were 50 members who danced and sang. In the sixth century BC, Thespis was the first real actor because he had a dialogue with the choir leader. In the 5th century BC Aeschylus proposed a second actor and reduced the chorus of 50 to 12 artists and then Sophocles added a third actor and increased the chorus of 12 to 15 artists, but reduced it to a commentary role in most of his works.

True. Usually 50 but then shrunk down to 12 or 15.

Read the following short passage.I started for school very late that morning and was in great dread of a scolding, especially because M. Hamel had said that he would question us on participles, and I did not know the first word about them. For a moment, I thought of running away and spending the day out of doors. It was so warm, so bright! The birds were chirping at the edge of the woods; and in the open field back of the sawmill the Prussian soldiers were drilling. It was all much more tempting than the rule for participles, but I had the strength to resist, and hurried off to school.

When I passed the town hall there was a crowd in front of the bulletin board. For the last two years all our bad news had come from there—the lost battles, the draft, the orders of the commanding officer—and I thought to myself, without stopping:
